Comparative Analysis of Antimicrobial Activity of Herbal Extracts against Pathogenic Microbes

Abstract

Antimicrobial activities of Spinacia oleracealeaf, Zingiberofficinalerhizome, Coriandrum sativum leaf, Allium sativum clove, Aloe vera gel and leaf was carried out against the multi-drug resistant strains using the minimum inhibitory concentration method. The direct TLC bioautography method is performed to identify the bioactive compounds present in the extracts exhibiting the antimicrobial property.All the plant extracts effectively inhibited the growth of pathogenic strains used in the study at a concentration of 250 to 31.25mg/ml. These results provide evidence that the tested plant extracts possess antimicrobial properties which can be tested further in the development of novel antimicrobial agents.
